Abstract

There is provided a host apparatus. The host apparatus includes: a display unit configured to display a user interface (UI) window for an image scanning apparatus. A control unit is configured to elevate and determine an optical scanning resolution of the image scanning apparatus according to Moire-related information. Using the Ul window a scanning resolution is input and a Moire removing function is selected. The image scanning apparatus is then controlled to perform a scanning operation according to the determined optical scanning resolution. A communication interface unit is configured to receive a scanned image. The scanned image is scanned with the optical scanning resolution in the image scanning apparatus. A filtering unit is configured to remove a halftoning screen pattern from the received scanned image. A sampling unit is configured to down-sample the filtered scanned image with the input scanning resolution.
